# About the Touch Screen
<Touch Screen equipped models>

The touch screen enables direct interaction with the VAIO computer using your finger(s).
You can perform various gestures on the touch screen instead of mouse operations, such as selecting items and scrolling.
Note

- Your VAIO computer is equipped with an optical touch screen. When using it, note the following characteristics of the optical touch screen.

- Your VAIO computer is equipped with two optical sensors and supports multi-touch input. When you rotate a picture on the touch screen, for example, a rotating gesture may not be successfully recognized by your VAIO computer, because it uses two optical sensors. This does not indicate a malfunction.

- To repeat tapping, be sure to lift your finger at least 4 mm off the touch screen after each tap.
  If you do not lift your finger enough, your repeated tap may not be recognized.

- If tapping triggers an unintentional operation, make sure that no other parts of your body, including your clothes, are in contact with the touch screen.

- Depending on the spot you touch on the screen, the touch screen sensitivity varies. This is normal and does not indicate a malfunction.

- The surface of the touch screen may get hot. This is normal and does not indicate a malfunction.

- Even though the surface of the touch screen is tempered glass, it could still become damaged. Treat it with adequate care. If it breaks, small granular shards may scatter and cause injury.
  Do not drop the touch screen or subject it to a strong impact. Do not scratch the surface. A surface flaw may cause the glass to break.

- A protection sheet is attached to the LCD screen frame at the factory. Remove the sheet before use; otherwise the touch screen may not work correctly.

- Some software does not accept touch screen operations.
